Set: It helps perform set performances like intersect, minus activity on the sub-search result.Selfjoin: Users utilize this command to join some of the outcome results together.Lookup : This helps to invoke some field values explicitly by using lookups.Join: It helps prepare a combination between two results, one is the main result, and the other is one of the pipeline searchings of the main result.Diff: This Splunk command helps return the proper difference between key product search results.Correlate: Calculating or identifying some of the correlation of two available fields.Cable, countable, contingency : Helping build key contingency tables between two fields.
Associate: Helping to identify a proper correlation between two fields explicitly. Arules: Helping to find some of the defined rules of association applicable for expected field values. Appendpipe: Helping to append some of the results came from the sub-pipeline, which applied to the available current result with a specific available current set. Appendcols: It does the same thing as above the primary additional benefit is that the first search result will consistently appear first, the second searching result will come second, and so on. Append: Using for appending some of the results from searching with the currently available result. Some of the basic commands are mentioned below: There are many commands for Splunk, especially for searching, correlation, data or indexing related, specific field identification, etc. #Splunk advanced search query examples software#

| from main where and more information about time modifiers, see Time modifiers.Start Your Free Software Development Course The end of the time range is the beginning of the current minute.
Here's an example of using a time range in a search that goes back 5 minutes, snapping to the beginning of the minute. For example, if it is 11:59:00 and you "snap to" using hours, you will snap to 11:00 not 12:00. When snapping to a time, Splunk software always '''snaps backwards''' or rounds down to the latest time that is not after the specified time.
To search for data from the beginning of today (12 AM or midnight) and apply a time offset of -2h, use This results in an earliest time of 10 PM yesterday. To search for data from the beginning of today (12 AM or midnight) use The symbol is referred to as the snap to and d is the time unit. 
To search for data using an exact date range, such as from October 15 at 8 PM to October 22 at 8 PM, use the timeformat %m/%d/%Y:%H:%M:%S and specify dates like earliest=":20:00:00" latest=":20:00:00". To search for data between 2 and 4 hours ago, use earliest=-4h latest=-2h. To search for data from now and go back 40 seconds, use earliest=-40s. To search for data from now and go back in time 5 minutes, use earliest=-5m. If you omit latest, the current time (now) is used. Use earliest=1 to specify the UNIX epoch time 1, which is UTC Januat 12:00:01 the latest time for the _time range of your search. You can specify an exact time such as earliest=":20:00:00", or a relative time such as earliest=-h or the earliest _time for the time range of your search. To specify a time range in your search syntax, you use the earliest and latest time modifiers. Specifying a narrow time range is a great way to filter the data in your dataset and to avoid producing more results than you really need. 
When you create a search, try to specify only the dates or times that you're interested in.
